[0002] The production equipment of the aluminum hot rolling production line is relatively precise. Extremely precise nozzles are arranged on the spray beams between the racks. The cooling control of the rolled products is achieved by controlling the nozzles. When there is a problem with the spray control, it will cause quality defects on the surface of the rolled products.

[0003] In the prior art, when there is a problem with the injection, a multimeter is used to detect the injection valve inside the injection beam to determine whether there is a problem with its control circuit. However, the structure of the injection valve is relatively precise, and the electrode to be tested of the injection valve is arranged at a relatively deep position, which is very inconvenient to measure with a multimeter, resulting in inaccurate measurement results. In addition, some rolling production lines have 6 injection beams on each group of rolling mills, and each injection beam has 44 nozzles. When using a multimeter for detection, at least two workers are required to cooperate, resulting in a large workload for detection, causing a long period of downtime, and affecting the production output of hot rolling.

[0030] In order to better understand the above-mentioned technical scheme, the above-mentioned technical scheme will be described in detail below in combination with specific implementation methods. It should be understood that the embodiments of the present disclosure and the specific features in the embodiments are detailed descriptions of the technical scheme of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0031] Figure 1 is a schematic diagram of a structure of a spray beam spray valve fault detection device provided in an embodiment of the present application, such as Figure 1 As shown, the device includes an indicator light 1, a metal probe 2 and a cable 3. There are two metal probes 2 and the length of the metal probes 2 is greater than a preset length threshold. The indicator light 1 includes two wiring terminals, and one wiring terminal is connected to one metal probe 2 through the cable 3.

[0032] Figure 2 A schematic diagram of the structure of an electrode to be tested in an injection valve provided in an embodiment of the present application is as follows: Figure 2 As shown, the connector 4 of the injection valve is connected to the electrode 5 to be measured through the cable 3. The electrode 5 to be measured is arranged in the screw hole 6. The screw hole 6 is very deep, and the electrode 5 to be measured is deep in the screw hole 6. Therefore, the probe of the multimeter sometimes cannot touch the electrode 5 to be measured, resulting in inaccurate measurement.

[0033] In this embodiment, the metal probe 2 is used to contact the electrode 5 to be measured of the injection valve. The length of the metal probe 2 is greater than a preset length threshold, which means that the metal probe 2 is an extended probe, which can ensure that the metal probe 2 can contact the electrode 5 to be measured arranged at a deep position. The indicator light 1 is used to indicate whether there is voltage on the electrode 5 to be measured. The indicator light 1 has two terminals, one of the two ends of the metal probe 2 is used as a measuring end, and the other end is used as a wiring terminal. One wiring terminal of the indicator light 1 is connected to a wiring terminal of the metal probe 2 through a cable 3.

[0034] Specifically, when detecting a certain injection valve, the power supply of that injection valve is turned on, and it can be turned off again after the detection is completed. After the power supply is turned on, the extended metal probe 2 of the device is inserted into the screw hole 6, touches the electrode 5 to be tested in the screw hole 6, and observes whether the indicator light 1 is on. It can be judged whether there is a problem with the control circuit of the injection valve, thereby achieving the purpose of quickly judging the failure of the injection valve. The two metal probes 2 respectively measure the positive and negative poles of the electrode 5 to be tested. When the electrode 5 to be tested has voltage, the device is powered on, the indicator light 1 will light up, and then it is known that the control circuit of the injection valve is connected. On the contrary, if the electrode 5 to be tested has no voltage, the indicator light 1 will not light up, and then it is known that there is a problem with the control circuit of the injection valve. The device can more easily and accurately detect whether the injection valve has voltage, and then it can be known whether the control circuit of the injection valve is connected. The device has a simple and compact structure and can be operated by one person, which improves the detection speed, shortens the maintenance time, and thus improves production output.

[0035] The indicator light 1 is a parallel light emitting diode.

[0036] In this embodiment, the indicator light 1 selects a parallel light emitting diode, so there is no need to distinguish between the positive and negative poles during measurement. No matter how the positive and negative poles are connected, the indicator light 1 will light up as long as there is voltage, thereby improving the measurement efficiency.

[0037] Figure 3 is a structural schematic diagram of another spray beam spray valve fault detection device provided in an embodiment of the present application, such as Figure 3 As shown, the device further comprises a box body 7 , and the indicator light 1 is arranged inside the box body 7 .

[0038] In this embodiment, a box body 7 is added to the device, and the indicator light 1 is placed in the box body 7, which can protect the indicator light 1 and increase the service life of the device.

[0039] Optionally, the box body 7 includes a detachable cover.

[0040] The box body 7 has a detachable cover, so that the box body 7 can be punched and closed. When the indicator light 1 needs to be replaced, the box body 7 can be opened to take out the indicator light 1, and then replaced with a new indicator light 1. After the replacement, the box body 7 can be closed.

[0041] like Figure 3 As shown, the device also includes a matching plug 8 and socket 9; an installation opening is opened on the box body 7, and the socket 9 is installed on the outer surface of the box body 7 through the installation opening. The indicator light 1 is connected to the socket 9 through the cable 3, and the plug 8 is connected to the metal probe 2 through the cable 3.

[0042] In this embodiment, the metal probe 2 and the indicator light 1 can be connected and separated through the plug 8 and the socket 9 .

[0043] The socket 9 is mounted on the outer surface of the box body 7, one end of the cable 3 is connected to the wiring terminal of the socket 9, and the other end of the cable 3 is connected to the wiring terminal of the indicator light 1. The plug 8 is also connected to the cable 3, and the other end of the cable 3 is connected to the wiring head of the metal probe 2. After the plug 8 is plugged into the socket 9, the device can be used to measure voltage.

[0044] Optionally, the socket of the socket 9 is a waterproof socket.

[0045] In this embodiment, considering that the injection valve is used to inject liquid, based on the special working environment, the socket 9 is preferably waterproof, so the socket 9 with a waterproof socket is selected.

[0046] like Figure 3 As shown, the device further includes a fixing block 10 , and two metal probes 2 are mounted on the fixing block 10 . The metal probes 2 are electrically connected to the indicator light 1 through the fixing block 10 .

[0047] It can be understood that installing the connection heads of the metal probes 2 on the fixing block 10 can fix the two metal probes 2 and protect the connection heads of the metal probes 2 to prevent damage to the connection heads during daily use.

[0048] like Figure 3 As shown, the fixing block 10 includes two rotating ends 11 , and the two metal probes 2 are respectively mounted on the two rotating ends 11 .

[0049] In this embodiment, the rotating end 11 can rotate, and the metal probe 2 is installed on the rotating end 11. When the rotating end 11 rotates, the metal probe 2 can be driven to rotate, so that the distance between the two metal probes 2 can be changed by rotating the metal probe 2, so that the electrodes 5 under test with different spacings can be measured.

[0050] Among them, there is a terminal on the rotating end 11, the metal probe 2 is connected to the terminal of the rotating end 11, and then the terminal is connected to the cable 3, and the other end of the cable 3 is connected to the terminal of the plug 8, or directly connected to the terminal of the indicator light 1.

[0051] like Figure 3 As shown, the outer side of the metal probe 2 is covered with an insulating shell 12.

[0052] In this embodiment, in order to protect the metal probe 2 and to provide insulation, an insulating shell 12 is provided on the outer side of the metal probe 2 .

[0053] like Figure 3 As shown, the length of the insulating housing 12 is less than that of the metal probe 2. The metal probe 2 includes a wiring terminal and a measuring terminal 13. One end of the insulating housing 12 is mechanically connected to the wiring terminal so that the measuring terminal 13 is exposed.

[0054] In this embodiment, the measuring end 13 of the metal probe 2 is not covered with the insulating housing 12 in order to facilitate the measurement.

[0055] Figure 4 is a schematic diagram of a metal probe structure provided in an embodiment of the present application, such as Figure 4 As shown, the metal probe 2 includes a probe inner core 21 , a spring seat 22 , a spring 23 , a contact piece 24 , a fixed block 25 and a movable block 26 .

[0056] The spring seat 22 is fixed on the inner wall of the insulating shell 12, and one end of the cable 3 passes through the insulating shell 12 and is connected to the base of the spring seat 22; one end of the probe core 21 passes through the movable block 26, the spring 23 and the fixed block 25 in sequence, and is fixedly connected to the contact piece 24 and points to the top seat of the spring seat 22, the fixed block 25 is fixed on the inner wall of the insulating shell 12 and is movably connected to the probe core 21, the movable block 26 is fixedly connected to the probe core 21 and is slidably installed on the inner wall of the insulating shell 12, the two ends of the spring 23 are respectively fixed on the fixed block 25 and the movable block 26, and the other end of the probe core 21 passes through the other end of the insulating shell 12 and is exposed to the outside.

[0057] It can be understood that the metal probe 2 has a telescopic function. When the exposed part of the probe core 21 is squeezed, the probe core 21 slides toward the inner side of the insulating shell 12 due to the squeezing force, and then drives the movable block 26 to move inward. The movement of the movable block 26 squeezes the spring 23, causing the spring 3 to shrink. The unsqueezed end of the probe core 21 moves inward until it drives the contact piece 24 to squeeze the spring seat 22. When the spring seat 22 is compressed to the limit, the probe core 21 stops sliding. At this time, a small part of the probe core 21 is still exposed to the outside to make good contact with the electrode 5 to be measured. When the exposed probe core 21 is no longer squeezed, the spring 23 pops outward, so that the probe core 21, the movable block 26 and the contact piece 24 return to their original positions. Among them, the fixed block 25 is used to fix the spring 23.

[0058] During measurement, the probe inner core 21 is slid partially into the insulating housing 12 , which can ensure the stability of the measurement and avoid short circuit caused by the connection of the two probe inner cores 21 when the two electrodes 5 to be measured are too close.

[0059] In this embodiment, in the fault handling, two persons are required to cooperate to eliminate each other, one person in the electrical room gives the output state of the injection valve, and one person measures the output voltage of the injection valve on site. Remove the quick plug connected to the injection valve body, quickly connect the socket 8 and plug 9 of the device, and extend the extended metal probe to the electrode 5 to be measured for measurement. Inform the operator in the electrical room to switch the valve and observe whether the DC24VLED indicator 1 is lit. If the DC24V LED indicator 1 is consistent with the injection valve switch control, it means that there is no problem with the control system. At this time, it is necessary to check whether there is a mechanical problem with the injection valve body. The device can more easily and accurately detect whether the injection valve has voltage, and then it can be known whether the control circuit of the injection valve is connected, and it can be operated by one person, which improves the detection speed, shortens the maintenance time, and thus improves production output.
